Despite what it says this plugin "Session Data Purge" is not a core plugin provided by the Joomla project and is something that you have installed

Wasn't this plugin only introduced in Joomla 3.8.6?

The manifest cache data isn't placed into the update SQL statement as the caches should be refreshed as part of the update process. Probably need to add the plugin to wherever that list is at these days.

@brianteeman see issue #19687

@sandewt Yes it was introduced in 3.8.6 - your report was confusing as I assumed you meant the values were present BEFORE the upgrade to 3.8.6

[sandewt]

@brianteeman The issue occurs in case of an update/upgade to 3.8.6. I found this at several sites.
And not in the case of a new installation. Maybe another can confirm this last.
